Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0043] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are to distinguish two entities with the same name but different parameters or parameters that are not the same, see "first" and "second" It is only for the convenience of expression, and should not be construed as a limitation on the embodiments of the present invention, which will not be described one by one in the subsequent embodiments.

[0044]An update event usually involves a collection of new streams or a collection of existing streams. Each flow in this set needs to compete for network resources on its path. However, the remaining bandwidth of the path may not provide sufficien...

Abstract

The invention discloses a network updating method and device. The network updating method and device comprises the following steps: obtaining the update events continuously, and establishing a queue of untreated update events with all untreated update events according to the small-to-large order of the arrival time of the update events; selecting an appointed number of non queued first update events and queued first update events randomly form the queue of the untreated update events, and calculating the update cost for all appointed update events; confirming the next update event to be processed according to the update cost of all appointed update events. According to the invention, by means of the network updating method and device, the fairness of updating the queued events and the the execution efficiency can be ensured simultaneously.

Description

technical field [0001] The invention relates to the field of communication engineering, in particular to a network update method and device. Background technique [0002] Network conditions are constantly changing due to network update events triggered by network operators, applications, and network devices. These update events include switch upgrades, network failures, VM (virtual machine) migrations, and more. When upgrading a switch, in order to ensure the normal operation of network applications, all flows through this switch should be migrated to other paths in the network. For VM migration, since the virtual machine is migrated to other servers in the network, all corresponding flows need to be migrated, thus generating a set of new flows that need to be migrated. This type of network update event has two consequences: a change in the network topology and a change in the traffic matrix. From the network point of view, a common cause of these update events is network...
